Most of these reflections would naturally occur to any unprejudiced person, and therefore upon a trial in this country, where we are so happy as to be under the protection of judges, who, by their education, studies, and habits, are above the reach of vulgar prejudices, and make it a rule for their conduct to suppose the accused party innocent till guilt be proved; with such judges, I say, there will be little danger of an innocent woman being condemned by false reasoning. But danger, in the cases of which we are now treating, may arise from the evidence and opinions given by physical people, who are called in to settle questions in science, which judges and jurymen are supposed not to know with accuracy. In general I am afraid too much has been left to our decision. Many of our profession are not so conversant with science as the world may think: and some of us are a little disposed to grasp at authority in a public examination, by giving a quick and decided opinion, where it should have been guarded with doubt; a character which no man should be ambitious to acquire, who in his profession is presumed every day to be deciding nice questions upon which the life of a patient may depend. To form a solid judgment about the birth of a new-born child, from the examination of its body, a professional man should have seen many new-born children, both still-born, and such as had outlived their birth a short time only; and he should have dissected, or attended the dissections of a number of bodies in the different stages of advancing putrefaction. I have often seen various common and natural appearances, both internal and external, mistaken for marks of a violent death. I remember a child which was found in a compressed state and globular form, and, like hardened dough, had retained all the concave impressions which had been made where any part of the skin and flesh had been pressed inwards. The jury had got an opinion that this moulding of the flesh could not have happened, except the infant had been put into that compressed state while it was alive. My anatomical employments enabled me to remove all their doubts about the fact. I offered to make the experiment before them, if they pleased; the child should be laid in warm water, till its flesh should become soft and pliable, as in a body just dead; then it should be compressed, and remain so till cold, and then they would see the same effect produced. They were satisfied, without making the trial. In many cases, to judge of the death of a child, it may be material to attend accurately to the force of cohesion between the skin and the scarf-skin: and still more, to be well acquainted with the various appearances of the blood settling upon the external parts of the body, and transuding through all the internal parts in proportion to the time that it has been dead, and to the degree of heat in which it has been kept.
